Calypso, just wondering if yours was a private sale where it was just you and the buyer. We've always purchased through a broker which leads me to believe that perhaps they simply don't want to get involved if the contract doesn't pass ROFR since they get their commission regardless.
Kansas, as someone else mentioned, did your buyer offer to pay maintenance fees for any 2004 points that are available. That seems to go a long way in getting through the ROFR process. Let us know what you decide to do.
